Police try to disperse people participating in a May Day rally in downtown Portland on Monday. Police in Portland said the permit obtained for the May Day rally and march there was canceled as some marchers began throwing projectiles at officers.

WASHINGTON — President Donald Trump tweeted today that the nation “needs a good ‘shutdown’ in September” to fix a “mess” in the Senate, issuing contradictory messages ahead of key votes on a spending plan to keep the federal government running.

Trump’s embrace of a government shutdown came days after he accused Senate Democrats of seeking a shutdown and obstructing majority Republicans during recent budget negotiations. Lawmakers announced Sunday they had reached an agreement to avoid a shutdown until September — a deal that does not include several provisions sought by Trump, including funding for a border wall.

Congress is expected to vote this week on the $1.1 trillion spending bill to fund the government through September. The White House on Monday praised the deal as a win for the nation’s military, health benefits for coal miners and other Trump priorities. The House is also considering a possible vote this week on a health care overhaul that would repeal and replace the so-called Obamacare law.

Kicking off the day, the president tweeted today from his Twitter account, “The reason for the plan negotiated between the Republicans and Democrats is that we need 60 votes in the Senate which are not there!” He added that we “either elect more Republican Senators in 2018 or change the rules now to 51 (percent). Our country needs a good “shutdown” in September to fix mess!”

WASHINGTON — United Airlines CEO Oscar Munoz apologized today on Capitol Hill for an incident in which a passenger was forcibly removed from a flight and vowed to do better as he and other airline executives faced tough questions from lawmakers.

“It was a mistake of epic proportions, clearly, in hindsight,” Munoz told a congressional hearing. He said passenger David Dao was treated in a way that no customer — or individual — should be treated, calling it a “terrible experience” that should never be repeated.

United has taken a series of steps to reduce overbooking of flights since the April 9 incident and will raise to $10,000 the limit on payments to customers who give up seats on oversold flights, Munoz said. The airline also said it will improve employee training.

“This is a turning point for United, and our 87,000 professionals,” a contrite Munoz said. “It is my mission to ensure we make the changes needed to provide our customers with the highest level of service and the deepest sense of respect.”

PORTLAND — May Day protests turned violent in the Pacific Northwest as demonstrators in Portland, Oregon, threw smoke bombs and Molotov cocktails at police while elsewhere thousands of people peacefully marched against President Donald Trump’s immigration and labor policies.

From New England to the Midwest to the West Coast people chanted and picketed against Trump along with the traditional May Day labor rallies. Protesters flooded streets in Chicago. At the White House gates, they demanded “Donald Trump has got to go!”

In Portland police shut down a protest they said had become a riot and arrested more than two dozen people. Police in Olympia, Washington, said nine people were taken into custody after several officers were injured by thrown rocks and windows were broken at businesses in Washington’s capital city.

In Seattle, five people were arrested during downtown protests and in Oakland, California, at least four were arrested after creating a human chain to block a county building where demonstrators demanded that county law enforcement refuse to collaborate with federal immigration agents.

The demonstrations on May Day, celebrated as International Workers’ Day, follow similar actions worldwide in which protesters from the Philippines to Paris demanded better working conditions. But the widespread protests in the United States were aimed directly at the new Republican president, who has followed aggressive anti-immigrant rhetoric on the campaign trail with aggressive action in the White House.

OLYMPIA, Wash. — Former Washington Gov. Mike Lowry, a Democrat who served in Congress for a decade, died Monday following complications from a stroke. He was 78.

Lowry, who was elected to one term as governor in 1992, was “a passionate defender of fairness for people and the environment,” according to a news release from his family.

“Mike was known as a courageous leader who was often willing to take early stands on sometimes controversial issues, and this courage, plus his straightforward nature, garnered respect from those in all political parties,” the statement said.

Lowry was a leading Democratic critic of President Ronald Reagan’s economic policies, even when they were wildly popular, and also fought against the arms buildup and restrictions on abortions.

Long an advocate of international trade that became crucial to the state, Lowry was credited with saving the Export-Import Bank’s direct loan program. He was on the House Budget Committee and worked on wilderness and marine sanctuary legislation and other issues.

Gov. Jay Inslee said Lowry “served with compassion and humility.”

CAIRO — After an American airstrike killed more than 100 Iraqi civilians in a house in the western part of Mosul in March, U.S. officials suggested the Islamic State group was to blame for the horrific toll, saying militants may have crammed the building with people, booby-trapped it with explosives, then lured in an airstrike by firing from the roof.

None of that happened, survivors and witnesses told The Associated Press, recounting the deadliest single incident in the months-long battle for the Iraqi city.

“Armed men in the house I was in? Never,” said Ali Zanoun, one of only two people in the building to survive the March 17 strike. He spent five days buried under the rubble of the building, drinking from a bottle of nose drops, with the bodies of more than 20 members of his family in the wreckage around him.

Instead, Zanoun and others interviewed by the AP described a horrifying battlefield where airstrikes and artillery pounded neighborhoods relentlessly trying to root out IS militants, leveling hundreds of buildings, many with civilians inside, despite the constant flight of surveillance drones overhead. Displaced families scurried from house to house, most driven out of their homes by IS militants, who herded residents at gunpoint out of neighborhoods about to fall to Iraqi forces and pushed them into IS-held areas.

Increased use of bombardment has made the fight for Mosul’s western sector, which began in mid-February, dramatically more destructive than fighting for its eastern half.

BALTIMORE — A car crash shattered Stuart Anders’ thigh, leaving pieces of bone sticking through his skin. Yet Anders begged emergency room doctors not to give him powerful opioid painkillers — he’d been addicted once before and panicked at the thought of relapsing.

“I can’t lose what I worked for,” he said.

The nation’s opioid crisis is forcing hospitals to begin rolling out non-addictive alternatives to treatments that have long been the mainstay for the severe pain of trauma and surgery, so they don’t save patients’ lives or limbs only to have them fall under the grip of addiction.

Anders, 53, from Essex, Maryland, was lucky to land in a Baltimore emergency room offering an option that dramatically cut his need for opioids: An ultrasound-guided nerve block bathed a key nerve in local anesthetic, keeping his upper leg numb for several days.

“It has really changed the dynamics of how we care for these patients,” said trauma anesthesiologist Dr. Ron Samet, who treated Anders.

HAMILTON TOWNSHIP, N.J. — Moderate Republicans face intense pressure on their party’s latest attempt to scrap Democrat Barack Obama’s health care law — from President Donald Trump, House GOP leaders, medical professionals and outside political groups.

Back home, their constituents provide little clarity.

In interviews, Associated Press reporters found views deeply held and deeply divided, reflective of dueling impulses to fulfill the seven-year-old GOP promise to repeal the law and to save many of its parts.

Meridene Walsh of Greenwood Village, Colorado, voted for Donald Trump for president last year partly because she wanted the Affordable Care Act gone. Now, she’s frustrated that House Republicans, including her own representative, Mike Coffman, are balking.

“The Republicans keep saying ‘repeal, repeal’ for seven years and a new president gets into office and what happens?” Meridene Walsh, 49, said with disgust as she stood outside a supermarket in the affluent Denver suburb. “I really want them to finish. Let’s get this health care thing going.”

LOS ANGELES — A tentative deal was reached between screenwriters and producers today, averting a strike that could have crippled TV and film production and inflicted harm on the wider California economy.

The three-year agreement, which requires ratification by members of the Writers Guild of America, was confirmed by the guild and producers’ spokesman Jarryd Gonzales shortly after the current contract expired early today. Further details weren’t immediately available.

The two sides held to a media blackout during negotiations that began March 13 and centered on compensation and health care.

The agreement spares the late-night shows that would immediately have gone dark without writers, and allows the networks to pursue their schedules for the upcoming TV season without interruption. Movie production would have felt a strike’s sting more gradually.

Guild members voted overwhelmingly last month to authorize a strike, and the WGA could have called for an immediate walkout today absent a deal. The previous writers’ strike extracted an estimated $2 billion toll on the state.

PROVIDENCE, R.I. — Innkeepers, restaurateurs and landscapers around the U.S. say they are struggling to find seasonal help and turning down business in some cases because the government tightened up on visas for temporary foreign workers.

“There’s going to be a lot of businesses that just can’t function on a full-time basis, and some might not even open at all,” said Mac Hay, who co-owns Mac’s Seafood on Cape Cod and has organized seasonal businesses to lobby Congress.

At issue are H-2B temporary visas, which are issued for workers holding down seasonal, nonagricultural jobs.

The U.S. caps the number at 66,000 per fiscal year. Some workers return year after year, and Congress has let them do so in the past without being counted toward the limit. No such exception was passed for 2017 at the end of last year, after the presidential election.

Lawmakers on Monday unveiled a government spending bill that would allow the homeland security secretary to increase the number of H-2B visas this fiscal year to almost 130,000.

AUSTIN, Texas — A student with a large hunting knife stabbed at least four people on the University of Texas campus, killing one and seriously wounding the others before surrendering to police, authorities said.

There was no immediate word about a motive.

Student Rachel Prichett said she was standing in line at a food truck outside a gym Monday when she saw a man with a knife resembling a machete approach the person standing behind her.

“The guy was standing next to me,” Prichett said. “He grabbed him by the shoulder and shoved the knife in it. I just started running as fast as I could.”

Police identified the suspect as 21-year-old Kendrex J. White.

LOS ANGELES — A tearful Jimmy Kimmel turned his show’s monologue into an emotional recounting of his newborn son’s open-heart surgery — and a plea that all American families get the life-saving medical care they need.

“It was a scary story and before I go into it, I want you to know it has a happy ending,” Kimmel assured ABC’s “Jimmy Kimmel Live” studio audience Monday as he detailed how his son’s routine birth last week suddenly turned frightening.

Several hours after his wife, Molly, gave birth April 21 to William John, a “very attentive” nurse at Cedars-Sinai Medical Center alerted the couple and doctors to the baby’s purpleish color and an apparent heart murmur, the host said.

The baby’s lack of oxygen was either due to a lung problem or, worst-case scenario, heart disease, Kimmel said, and it was determined to be the latter.

“It’s a very terrifying thing,” he said. He was surrounded at the hospital by very worried-looking people, “kind of like right now,” he told the audience, one of the jokes he managed despite choking up and having to pause at times.
